Northampton, MA – National Priorities Project (NPP) has released unprecedented analysis tracking federal tax breaks every year from 1974 to the present. Tax breaks have grown in number and size, meaning the U.S. Treasury has less money to spend on initiatives ranging from early-childhood education to infrastructure repairs to food safety.

NPP’s analysis and accompanying interactive visualization not only track a host of tax breaks over the past 40 years – from capital gains to the home mortgage interest deduction to corporate loopholes – it also examines who benefits the most from the existing tax code.

“From the perspective of the government, tax breaks are no different from any other kind of spending,” said Mattea Kramer, Director of Research for NPP. “Yet tax breaks receive little or no oversight by lawmakers once they’re written into the tax code, even as they cost the U.S. government an estimated $1.13 trillion this year – as large as all discretionary spending.”

Some key findings from the report include:

Corporate tax breaks will total $108 billion in FY 2013 – more than 1.5 times what the U.S. government spends on education funding. Between 2007 and 2013, the revenue lost from U.S. corporations deferring taxes on income earned abroad rose 200%, going from $14 billion to $42 billion.

All tax breaks for individuals will exceed $1 trillion this year, with about 17% of the biggest individual tax breaks going to the top 1% of earners. In fact, many individual tax breaks disproportionately benefit wealthy households.

Between 1974 and 2013, the fastest-growing tax break in terms of lost revenue was the exclusion of employer-sponsored health care, a deduction that many people don't even know exists.
